AUTOMATIC GRAIN-BINDER.

.SPEQEFIATEN forming part of Letters Patent No. 677,553, dated July 2,1 1901. Application filed April 11, 1901. Serial No. 55,304. (No model.)

To @ZZ whom t muy concern:

Be it known that I, JOHN F. APPLEBY, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Automatic Grain-Binders, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure l is a side elevation of so much of an automatic grain-binder as necessary to show my invention. Fig. 2 is a side elevation of those parts of an automatic'grainbinder which I have introduced consisting of means for driving the packer-shaft intermittently. Fig. 3 is a perspective View of the parts provided for supporting 'the packershaft in such a manner that the shaft, and consequently the gear upon it, may be'moved into and out of mesh with the constantly-rotating gear by which it is driven; and Fig. 4 is a plan view of the packer-shaft, its gear, and the rocking support E.

A is the main frame of an ordinary Appleby binder. Vithin its lower member is the needle-shaft o. In the upper member is the knotter-driving shaft a.

The knotter and bundle discharging devices are not shown, as they form no part of the present invention.

Bis a gear upon the shaft a', which is driven by a housed pinion on the shaft b. This shaft is intermittently rotated by the usual clutching devices upon the shaft C. The shaft C rotates constantly and the pinion c is keyed directly thereto.

D is a part of the binder-frame, which for lightness is usually made of gas-pipe.

In Fig. 2 the arrangement of the gearing may be best understood. The gear c upon the shaft C is constantly rotated, as stated. Upon a suitable stud, supported upon the main frame, is the intermediate gear c. Upon the gas-pipe D is a rocking support E, having arms supporting the bearings e and e. The lever e2 is as one piece with the rocking support E, by means of which lever said rocking support is connected to the intermittently workin g parts of the binder. Upon the crank-wrists e3 and e4 of the packer-shaft F are the packers F and F, connected at their lower endsby the links f and f to a fixed portion of the machine at f3.

Gr is the needle. the axis of the needle is a pivot g. Upon this pivot is placed the socket g', into which the lever e2 passes freely.

The object of my invention may be best understood by reference to Fig. 2, in which a constantly-driven gear c imparts rotation to the intermediate gear c' and the constantlyrotating intermediate gear c to the intermittently-rotating packer-shaft gear f2. When the parts are in the position shown, the packers are in operation; but when the binding mechanism is put in motion the movement of the needle causes the lever e2, and consequently the arms e and e' of the rocking support E, to rise, and thereby lift the packershaft F and move its gear f2 out of mesh with the gear c. Because of the fact that the pivot g moves some distance laterally as well as upward the arm e2 is, in fact, made extensible by the use of the socket g.

In order that the depth of mesh of the gears, particularly the intermediate gear c with the packer-shaft gear f2, shall be detinite,I shroud the teeth as far up as the pitch-circle. The result in the action of the gears is that the pitch-line shrouds roll together, thus forming an automatic stop. As here illustrated, the constantly-driven gear c moves in the direction indicated by the arrow. As it is necessary to move the packer-shaft in the same direction, the intermediate gear c is used and the packer-shaft gear f2 permitted to intermittently mesh with it. In machines where the shaft o rotates in a reverse direction the intermediate gear c may be dispensed with, the only change necessary being to move the position of the shaft C or enlarge the gears c and f2. 4

What 'I claim as my invention, and desire to secure by Letters Patent, is-

1. In anautomatic grain-binder, the combination with a constantly-rotating drivingshaft and a binding mechanism actuated thereby, of an intermittently-rotatin g packershaft, a rocking support in which said packershaft is journaled, gears mounted upon said driving-shaft and packer-shaft, and means At a point eccentric to IOO actuated by said binding mechanism for rocking said support, thereby moving the packershaft gear into and ont of mesh with the driving-shaft gear, or gear actuated thereby, substantially as described.

2. In an automatic grain-binder, the combination with a constantly-rotating drivingshaft andl a binding mechanism actuated thereby, of an intermittently-rotating packershaft, a rocking support in which said packershaft is journaled, spur-gears mounted upon said driving-shaft and packer-shaft, an oscillating needle-shaft and a mechanism connecting said needle-shaft with said rocking support whereby the oscillation of the needleshaft shall rock the support and thereby move the packer-shaft into and out of mesh with the driving-shaft gear or gear actuated thereby, substantially as described.

3. In an automatic grain-binder, the combination with a constantly-rotating drivingshaft, and a binding mechanism intermittently actuated thereby, of an intermittentlyrotating packer-shaft, a rocking support in which said packer-shaft is journaled, spurgears secured to the said driving-shaft and packer shaft', an intermittently Vibrating needle, and a connection between said needle and said rocking support whereby the vibration of the needle shall rock the support and thereby move the packer-shaft gear into and out of mesh with the driving-shaft gear or gearactuated thereby, substantially as described.

4. In an automatic grain-binder, the combination with a constantly-rotated drivingshaft, and a binding mechanism intermittently actuated thereby, of a constantly-rotated gear actuated by said driving-shaft, an intermittently-rotating packer-shaft, a rocking support in which said packer-shaft is jonrnaled, a spur-gear secured to said packershaft, an intermittently-vibrating needle, and an extensible connection between said needle and said rocking support'whereby the vibration of the needle shall rock the support and thereby move the packer-shaft gear into and ont of mesh with said constantlyrotated gear, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
